The main feature of mould of the present invention is as follows:
(1) because station spacing is large, die area is also relatively large, and for ensureing stepping accuracy and facilitating process and assemble, mould is formed by 4 piece piece respectively.Part 1 from station 1 to station 4, include rush correcting pin-and-hole, rush technical gaps, local form's trimming operation content; Part 2, from station 5 to station 6, is little ladder drawing and beading, shaping unit; 3rd part, from station 7 to station 8, comprises that local form is die-cut, mark embossing process steps content; 4th part is from station 9 to station 10, comprise punching, cut-out, large ladder drawing sequence content, cut off due to carrier and large ladder drawing coexists on station 10 and completes, for guaranteeing first to cut off rear drawing, the length cutting off punch should exceed the thick height above of 1 material than drawing die; Concave template 5, stripper 7, backing plate 4,10 and fixed head 9 are all designed to the version that 4 large module edges are spelled.
(2) mould adopts the feeding of Pneumatic automatic feeding device to hold concurrently pre-determined bit, to be held concurrently material lift, make fine positioning by pilot pin 60 by stock guide, slot type buoyant bar guiding.The distance precision of entering of mould is ± 0.01mm, the automatic feeding precision adopted is ± 0.05mm, for this reason, be provided with bilateral carrier and the technology hole of 22 Φ 4mm be located in the symmetric position of band material each station both sides, both sides carrier, and be equipped with suitable pilot pin, realize the accurate location to band material, pilot pin selects H7/h6 with coordinating of stripper.Stock guide 6 is contained in the front end of station 1, is respectively arranged with 23 groups of totally 46 buoyant bars 51 between each station of mould.For ensureing the band certain guiding accuracy of material and sending at the smooth and easy of punching course, the one side gap of 0.05 ~ 0.25mm between band material width and slot type buoyant bar, should be had.Highly in sustained height plane, must therefore require that the size of each buoyant bar is consistent after the assembling of buoyant bar.Because the forming height of the little ladder of product is 8mm, during large joggling, product is separated with carrier, and its forming height does not affect sending to of billot, so the distance that billot is floated off die face by buoyant bar is designed to 10mm, concrete structure is shown in the K-K sectional view in Fig. 2.
(3) consider that material is thick and only have 0.6mm, therefore for rushing the blank operations such as process-cut, outline die, cut-out except guarantee good guidance, its stability of special concern.In order to improve the precision of mould, adopt elastic tripper.Elastic tripper not only plays discharging effect after punching press is complete, also plays binder effect, effectively prevent slippage or the distortion of material in punching course before punching press starts.The each several part of segmentation is also respectively provided with 4 pairs of auxiliary guide between punch retainer, stripper, concave template; namely little guide pillar 50, little guide pin bushing 49 lead; make that whole punch die guiding accuracy is high, rigidity is large, action stability good, small punch is led protective effect in addition meanwhile.The fit clearance of punch and stripper is 0.012mm, and the fit clearance of little guide pillar and little guide pin bushing is 0.006mm.Stripper stroke is 16mm, according to size and the range demands of stripping force, selects altogether medium-sized Rectangular Spring SWM35mm × 75mm72, SWM25mm × 85mm27.
(4) feeding detection device is by mistake installed on station 8 position.When billot sends error to, not in place, the head detecting pilot pin 58 cannot enter in the correcting pin-and-hole of billot; but touch above billot; while detection pilot pin is retreated, force feeler lever 57, move outward; the microswitch 56 be fixed on outside fixed head is made to send signal; forcing press stops punching press when receiving the signal that microswitch sends automatically, and the punch be now fixed in patrix not yet enters die, thus prevents punching by mistake; protect mould, also prevent from producing a large amount of waste product.
(5) structural design of punch and matrix: rapid wear small punch adopts quick change mount fixing structure.As punching 2 ×
Φthe small punch 22 that 4mm correcting pin-and-hole is corresponding is more easily broken consumable accessorys.Under normal circumstances, changing punch must take punch retainer and upper bolster apart, bothers very much, and meanwhile, dismounting often, also can affect mould and die accuracy.The fixing employing plug screw of this mould small punch and the quick-changing type structure of pad capital pressure.When needing repairing and change punch, only plug screw 52 need be pulled down, then releasing pad post 53 and punch from stripper to punch retainer direction.After having changed small punch, then load pad post and plug screw from upper bolster direction successively, concrete structure is shown in the C-C sectional view in Fig. 2, and punch and fixed head adopt H6/h5 to coordinate.
For the ease of processing, assembling, adjustment and maintenance, except round punch, each special-shaped blanking punch is all designed to through type, so that linear cutter is shaped, part punch structure is as shown in Fig. 7,9,11,13,15,17,19,21.The special-shaped punch that size is less, is fixed on punch retainer with riveting method, and working portion heat treatment hardness is 58 ~ 62HRC, is then 32 ~ 38HRC with punch retainer 3 part hardness, is beneficial to riveted joint.Larger-size punch is lifted on upper bolster by fixed head, and length dimension exceeds 2mm than small punch, realizes ladder stamping-out, is conducive to reducing blanking pressure.
All punchings, die-cut and female die for forming all adopt the version of straight-through bushing (or insert), and female die embedding cover and concave template adopt H7/n6 interference fits, and part female die embedding cover is as shown in Fig. 8,10,12,14,16,18,20,22.
